All recent statements by Chinese scientists about the successful creation and testing of the EmDrive microwave rocket engine are most likely based on erroneous data, but the device itself does not violate the laws of physics in any case, says physicist Bra

After some lull, news of the "impossible electromagnetic motor" returns

For every action there is an equal and opposite action

At the end of 2016, a surprising message spread around the world news agencies: China is testing the "impossible" EmDrive engine in space. The one that seems to violate the law of conservation of momentum. Let's try to figure it out?

Short:- why modern physics has reached a dead end.- Salik.biz- that Einstein and Hawking did not have time to explore.- how to combine quantum mechanics and general relativity.nWith the help of the Internet, you can learn everything - from the design of an internal combustion engine to the speed of expansion of the Universe

An international group of physicists conducted two experiments, during which the researchers were able to register particle behavior that is not typical for three-dimensional space

Time - it is what prevents everything from happening at the same time. " Physicist John Wheeler's statement rightly summarizes what time does as opposed to anything else

Reality - this is a rather relative concept. What is really real? What we see, hear and feel or what we are unable to notice with our senses?

We are accustomed to the three dimensions of our Universe - in length, width and depth

Russia must quickly establish a reliable system of protection against hypersonic weapons. This was discussed at traditional meetings with President Putin on the defense industry in Sochi. The Supreme Commander-in-Chief recalled that so far no one except Russia has this weapon

Cryonics - it is a technology of keeping the body (and in some cases the brain) in a state of deep cooling, but with the maintenance of all vital functions

You may not have known this, but bears are far from the only animals that can hibernate. Various types of squirrels, bats, and even some birds can also lower their body temperature by immersing themselves in a dormant state for weeks or even months

The era of silicon technologies is coming to an end, giving way to a new "material of the future" - gallium nitride!Anker recently unveiled its new tiny power supply. According to the company, such a small size of the device is due to a component that was used instead of silicon, namely, gallium nitride (GaN)

Imagine a picture familiar from cinema: a hypnotist induces a patient into a trance state, holding a pendulum on a thin thread in front of his eyes. Hypnosis is a poorly understood phenomenon; if some do not doubt the need for its use, others consider it quackery and nothing more

Since 2011, scientists from around the world have tried to create artificial leaves that can clean the air and even produce fuel

The ancient Indians knew about stem cells and conducted research in this area, and Newton and Einstein were wrong in their calculations - such theses were voiced in reports at the annual meeting of the Indian Scientific Congress

Few people know about this engineer, and even less write about him. Apparently, this is due to the fact that Alexanderson himself never sought to be famous, bathe in the rays of glory, and participate in scandals. He worked, invented, designed … In total, he has almost three hundred and fifty patents, the last of which he received at almost ninety years old!A

Children see the world a little differently, a fact. They do not have a narrow-mindedness of consciousness and thinking, they are not yet familiar with the cliches and patterns along which the thoughts of an adult move. From this, their "small" brains give birth to sometimes unique things that literally change our world

When 69-year-old Peter Brown retired from his job as a pilot, he decided to embark on a whole new mission: to create the perfect breakfast for his wife. After all, breakfast is the most important meal of the day. One bad thing is that unless you're a morning person, making a real good breakfast can be a difficult, impossible task

Probably, this scientist remained one of the most underestimated geniuses of Russian mathematical science.Stop walking mechanism.- Salik.bizPerhaps the most spectacular invention of Pafnutiy Chebyshev is his plantigrade machine.Although it cannot be argued that this is his most famous invention

The devices that truly improved human life - such as electricity, the telephone, and the plane - were created by people who passionately believe that their inventions will make the world a better place. It looks like Troy Reed from Tulsa, Oklahoma is that kind of person

In the development of our civilization, various inventions play a huge role, which act as an engine, an assistant for all mankind. As in many other countries of the world, the USSR had talents, many inventors, engineers, designers, who presented to mankind useful products and technologies that made it possible to make a breakthrough in one direction or another

Low-temperature fusion in the USSR fell victim to the clan struggle of officials, and now these ideas have found development in the West in the form of the Rossi reactor. I dare to suggest that in the bowels of our planet there are all the conditions for the low-temperature reaction of copper synthesis from nickel in a hydrogen atmosphere, experimentally carried out in a reactor

Danil Luminarsky from the 22nd Krasnoyarsk school invented an electronic analogue of a guide dog. The device is intended for visually impaired people. In an ordinary cane, the inventor mounted a control panel, as well as analogs of a navigator and parking sensors

The twentieth century was an era of continuous discoveries in the field of science and technology. However, this pace often becomes a problem for those who study the history of progress. The thing is that a lot of inventions could appear in two, and even in three countries practically simultaneously and independently of each other

Many people know about Nikola Tesla, about his inventions, including his experiments on the transmission of energy over a distance.But not many people know at all that back in 1900, the Russian scientist Mikhail Mikhailovich Filippov "went to Riga, where he carried out, in the presence of some experts, experiments on blasting at a distance

Everyone loves to talk about possible scenarios. What if Nikola Tesla had realized the idea of wireless endless electricity, or nuclear energy had not been discovered, or plastic had not been introduced into use, then our world would have been completely different. And

The Russian self-spinning wheel is not only the simplest hand-spinning machine, but also a wonderful work of art. We want to tell you about one of these old self-spinning wheels. It is kept in the family of Anna Mikhailovna Orekhovskaya from the village of Levkovo, Vyazemsky district, Smolensk region

The history of Alfred Hubbard's invention dates back to 1919. It was then that the inventor, who was only sixteen years old, showed the journalists of the "Seattle Post" a certain mechanism.
